During June 2025, Mitch Cairns focused on improving input calibration reliability for Nintendo Switch controllers in the shadps4-emu/ext-SDL repository. He addressed a critical bug affecting thumbstick calibration by correcting the parsing order of max and min values for the right stick’s X and Y axes. Working in C and leveraging his expertise in driver development and embedded systems, Mitch implemented the fix in a single, targeted commit. He validated the solution through focused testing within the ext-SDL integration path, ensuring no regressions for other input devices. This work reduced calibration discrepancies and enhanced the accuracy of emulated Switch input.
